The US has launched a new round of sanctions targeting Iran’s shadow oil fleet and financial networks to cut off funding for the IRGC and proxy groups.

The United States has announced a fresh wave of sanctions targeting Iran’s "shadow oil economy," accusing the regime of using illicit petroleum revenues to finance the Islamic Revolutionary Guard Corps (IRGC) and regional proxy groups [1]. The measures, which designate over 50 companies, individuals, and vessels, are part of a broader "Economic Fury" campaign intended to intensify financial pressure on Tehran [2].

**Key takeaways**
* The US Treasury and State Department have sanctioned more than 50 entities, individuals, and vessels involved in Iran's petroleum and financial networks [2].
* Sanctions target a "shadow fleet" of tankers and a Hong Kong-based network accused of moving tens of millions of barrels of oil worth billions of dollars [1].
* The US is targeting the Amin Exchange, a foreign currency house, and its front companies in the UAE, Turkiye, China, and Hong Kong [2].
* The Rewards for Justice program is offering up to $15 million for information to help disrupt IRGC financial operations [1].
* Washington has warned global traders and financial institutions that cooperating with Iran’s energy trade carries the risk of secondary US sanctions [2].

## Dismantling the Shadow Financial Network
The latest US action focuses on severing the financial lifelines that support Iran’s military apparatus [1]. According to the US Treasury, the sanctioned Amin Exchange and its associated front companies facilitated hundreds of millions of dollars in transactions for sanctioned Iranian banks and entities linked to the oil and petrochemical sectors [2]. US Treasury Secretary Scott Bessent stated that the administration is systematically dismantling Iran’s "shadow banking system" to prevent the regime from manipulating international finance to fund its activities [2].

In addition to financial firms, the State Department has designated eight entities and identified eight vessels as "blocked property" for their roles in transporting Iranian petroleum [1]. The Treasury Department also sanctioned 19 specific vessels, including the Barbados-flagged *GREAT SAIL* and the Panama-flagged *SWIFT FALCON*, for moving Iranian-origin oil, methanol, and liquefied petroleum gas [2]. US officials allege that these shipments generate hundreds of millions of dollars for the Iranian regime, which are then used to support regional aggression and global terrorism [1].

## Why it matters
These sanctions represent a continuation of Washington’s "maximum economic pressure" campaign against Tehran, which remains a central pillar of US policy amid ongoing tensions regarding Iran’s nuclear program and its support for armed groups in West Asia [2]. By targeting the "dark fleet" and the financial nodes that facilitate these trades, the US aims to disrupt the revenue streams that fund the IRGC and its overseas operations, including groups like Hamas and Hizballah [1]. Washington has issued a clear warning to global companies and "teapot" oil refineries in China that any entity found supporting Iranian commerce faces the risk of exposure to US secondary sanctions [2]. The US government continues to seek intelligence on these illicit financial schemes, offering significant rewards for information that could further impede the IRGC’s ability to generate revenue [1].
